TJ - apols. I meant to have included one of these to indicate I was joking:

None intended. Not least because I tend to agree with your recipe approach. Leaving out the orange squash, what proportions of salts do you include for, say, 100g of maltodextrine?

Just trying to work out if I can sack off the nuun tablets.

Oh, and mikey - we didn't know you wanted to take it abroad.... In which case, just buy some from Decathlon (or Tesco - they often have it in the big stores) and don't break the seal before you get on the plane..!

borrowed a friends bottle mid way though a 100mile sportive, gave me horrendous stomach cramp, had to stop and walk arround a bit till it dissapeared.

Went back to water, flapjack and bannanas after that with no problems.

Definately try it out with a sachet first. Now I just stick to homemade flapjack, a particularly sticky recipie with a little added salt (small teasoon lo-salt in a days worth) and a fair bit more sugar than normal.
